If the user uses any of the flow and sensor units, it is necessary to inform the sensor factor. If none of the available units are required, you will need
to calculate the user factor by relating the parameters "User Unit", "Sensor Unit"
and "Sensor Factor", and fill it in so that the device correctly
converts the pulses to the required unit. In this case,
LogBox Wi-Fi
will
convert the pulses to the user unit as follows:
●
User Value = (Count)/(Sensor Factor)*(User Factor)
○
It is necessary to consider that the log range is 1 second and will not influence the calculation. Internally,
LogBox Wi-Fi
always considers
the log range.

Let’s say, for example, that an application has a PNP-type sensor that computes a produced part every 30 rising-edge pulses and that the user
wants to visualize the production in parts per minute. The following parameters must have been configured on the device’s digital input:
•
Log Range:
It must be configured to log the maximum sensor frequency.
•
Input Mode:
Pulse Count.
•
Sensor Type:
PNP.
•
Counting Edge:
Rise.
•
Unit and Sensor Unit:
Custom.
•
Sensor Factor:
30 (pulses/part).
•
User Factor:
60 (conversion of parts per second to parts per minute).
Thus,
LogBox Wi-Fi
will record the number of pulses occurring within that period at each log range, and every time the data is displayed, it will
transform those pulses into the number of parts produced per minute (user-customized unit).
In the same example, it is possible to assume that the log range is 20 seconds. Thus, if the sensor gives 20 pulses per second, the
LogBox Wi-Fi
will register 400 pulses per range, displaying 40 parts per minute (((20 pulses/s)/(30 pulses/part)) * 60 (1 min) = 40) for the user.

EVENT LOG
If the digital input is configured in the "Event Log" mode, each selected edge will create a log in memory, informing the event and the instant that it
occurred. This log will not be synchronized with the periodic logs, but will respect the logs beginning and end modes. Events will be logged after the
end of the
debounce
time set and will be logged with the
debounce
time delay.
LogBox Wi-Fi
can log up to 10 events within 1 second.
5.2.3
LOGS CONTROL
It is possible to use the digital input to start and/or pause the logs of the other input channels. Once configured in the "Logs Control" mode, each
selected edge will start or stop the process of in-memory logs. As in the "Event Log" mode, detected events will only act after the configured
debounce
time expires. Thus, the start/pause of the logs will be performed with the
debounce
time delay.
